8mm DC Motor Low Power Consumption Model NFP-D0812

Coreless Motor Model NFP-D0812 Data Sheet

Coreless motor is similar to a cored DC motor in that it has brushes and a commutator. However, the difference is that the rotors windings are wound in a skewed (or honeycomb) fashion to form a self-supporting hollow cylinder, which is usually epoxied for stability.
